Welcome. I'm pulling a light weight 5er with my 2014 Ram 2500 CTD 4X4 and getting about 11 1/5 MPG by the EVIC. Only have 5600 miles on it now. I think it will do better after it gets broken in.
I've got 6,675 miles on my truck (just checked with my OnStar app) . . . last time I towed the trailer I had just under 2,000 miles on it.
I'm hoping I'll get better mileage when I pull next time in January when we go to the HOC Rally in Arizona now that it is broken in.
I've been mostly a Dodge truck guy over the years (have had 3 Ford trucks, 5 Dodge trucks, and now my first Chevy truck) . . .
So far, my new Chevy truck has amazed me beyond my expectations!
That 4.10 rear end is simply awesome!
Old and New:
I do miss that Dodge 1500 4x4 . . . my most favorite vehicle I've ever owned!
It is now residing in Rochester, NY, and the new owner is having great luck with it!
Had 164,000 miles on it when I sold it to him, and he has put 11,000 more miles on it pulling his car collection (four hot rods) from Denver to New York, and the only issues he has had was a burnt out headlight and the headlight switch burned out (which I think was caused by something in his car trailer wiring) . . .
